Propeller Size?????

[18Parker]

I have a 18' CC Parker with a Yamaha 130 Saltwater Series on the back. My boat is at the coast so I can't measure the currrent prop size; however, I want to order one before I go back down there. Does anyone know where to find out the size or does anyone have any suggestions as to what size I would want to run on it?? Any help would be greatly appreciated.
